SASKATOON -- A Saskatoon family of 12 is isolating in one household after four children tested positive for COVID-19.

Rachel Smith says she received a notice from her kids' school on March 18 saying there was a positive case of COVID-19.

While she wasn’t sure the positive case was in any of their classes, she pulled the children from school right away. 

"The following day my daughter was complaining of a headache and she’s the only one who had symptoms," Smith told CTV News. 

On March 20 Smith loaded up her van and took six children to get tested.

"I was just very shocked to find out that four of the kids were positive for COVID as three of them did not have symptoms." 

Under the one roof are three adults and nine children - five of her own and the four of her sisters’ who she took in after she died in December. 

The children who tested positive were put to isolation in the "COVID wing" of the house where they share two bedrooms and a bathroom. 

Smith said the kids, aged five, eight, 11 and 13, have their own game systems, Netflix, laptops and other essentials to keep them busy.

"We were lucky that the kids were a little bit older, they were able to isolate easily," Smith said. 

"They didn’t mind being in their room; they didn’t mind getting breakfast, lunch and dinner delivered to them. They’re actually pretty happy." 

The house also has a large deck for members of the family to get fresh air.

Smith and her sister Johanna Angus, who live in the home, have tested negative twice and tend to the children daily, constantly cleaning to prevent further COVID-19 cases in the family. 

With online learning, Smith says she helps the kids with 12 Zoom classes a day and manages the family with a physical schedule and "lots of lists." 

"The Centers for Disease Control says that household spread is common and quick and frequently asymptomatic and everyone needs to be on guard," Cynthia Carr, an epidemiologist with EPI Research Inc., told CTV News.

Carr says kids with COVID-19 should be conscious to frequently wash their hands and to cough and sneeze into Kleenex to prevent droplets from spreading. 

"It would be beneficial if everyone kept their masks on in the home, particularly if you’re in any shared rooms. Even if you’re not it’s better to keep the masks on because the airflow could be going from room to room." 

The family is taking the positive cases and helping by giving a positive outlook on the situation. When the family went out to get tested, they even filmed a TikTok out the experience. 

As of Tuesday at midnight the children will be deemed COVID-19 recovered but will remain in isolation until April 4, Smith said.
